Looking for Adcocks in Joelton, TN area

I am looking to find families of Adcocks who lived in the area of Joelton, TN.My ancestor is Elizabeth Adcock, b abt 1817 VA, who married Christian Coleman in Davidson Co, TN in Feb of 1834. This family lived in Robertson Co, TN (1850 census)-a Joel Adcock is listed in the household in 1850-but they later moved to the Joelton area, where my grandfather was born in 1881.
